Effect of viscoelastic fluid on the lift force in lubricated contacts
Shiyuan Hu, Fanlong Meng, Masao Doi
We consider a cylinder immersed in viscous fluid moving near a flat substrate covered by an incompressible viscoelastic fluid layer, and study the effect of the fluid viscoelastici…
Scaling transition of active turbulence from two to three dimensions
Da Wei, Yaochen Yang, Xuefeng Wei +4
Turbulent flows are observed in low-Reynolds active fluids. They are intrinsically different from the classical inertial turbulence and behave distinctively in two- and three-dimen…
Shear hardening in frictionless amorphous solids near the jamming transition
Deng Pan, Fanlong Meng, Yuliang Jin
The jamming transition, generally manifested by a rapid increase of rigidity under compression (i.e., compression hardening), is ubiquitous in amorphous materials. Here we study sh…
Field-controlling patterns of sheared ferrofluid droplets
Shunichi Ishida, Yaochen Yang, Fanlong Meng +1
We investigate how ferrofluid droplets suspended in a wall-bounded shear flow can organise when subjected to an external magnetic field. By tuning the magnitude of the external mag…
Scaling regimes of active turbulence with external dissipation
Berta Martínez-Prat, Ricard Alert, Fanlong Meng +5
Active fluids exhibit complex turbulent-like flows at low Reynolds number. Recent work predicted that 2d active nematic turbulence follows universal scaling laws. However, experime…
Magnetic microswimmers exhibit Bose-Einstein-like condensation
Fanlong Meng, Daiki Matsunaga, Benoît Mahault +1
We study an active matter system comprised of magnetic microswimmers confined in a microfluidic channel and show that it exhibits a new type of self-organized behavior. Combining a…
Modelling Mullins Effect Induced by Chain Delamination and Reattachment
Daoyuan Qian, Fanlong Meng
We propose a continuum theory to model the Mullins effect, which is ubiquitously observed in polymer composites. In the theory, the softening of the materials during the stretching…
Designing metachronal waves of cilia
Fanlong Meng, Rachel R. Bennett, Nariya Uchida +1
On surfaces with many motile cilia, beats of the individual cilia coordinate to form metachronal waves. We present a theoretical framework that connects the dynamics of an individu…
Drying Pathways of an Evaporating Soft Matter Droplet
Guangle Du, Fangfu Ye, Masao Doi +1
Micro-droplets of soft matter solutions have different morphologies upon drying, and can finally become wrinkled, buckled or cavitated particles. We investigate the morphology evol…
Degenerate states, emergent dynamics and fluid mixing by magnetic rotors
Takuma Kawai, Daiki Matsunaga, Fanlong Meng +2
We investigate the collective motion of magnetic rotors suspended in a viscous fluid under an uniform rotating magnetic field. The rotors are positioned on a square lattice, and lo…
Far-field theory for trajectories of magnetic ellipsoids in rectangular and circular channels
Daiki Matsunaga, Andreas Zöttl, Fanlong Meng +2
We report a method to control the positions of ellipsoidal magnets in flowing channels of rectangular or circular cross section at low Reynolds number.A static uniform magnetic fie…
Clustering of Magnetic Swimmers in a Poiseuille Flow
Fanlong Meng, Daiki Matsunaga, Ramin Golestanian
We investigate the collective behavior of magnetic swimmers, which are suspended in a Poiseuille flow and placed under an external magnetic field, using analytical techniques and B…
Focusing and sorting of ellipsoidal magnetic particles in microchannels
Daiki Matsunaga, Fanlong Meng, Andreas Zoettl +2
We present a simple method to control the position of ellipsoidal magnetic particles in microchannel Poiseuille flow using a static uniform magnetic field. The magnetic field is ut…
Nonlinear elasticity of semiflexible filament networks
Fanlong Meng, Eugene M. Terentjev
We develop a continuum theory for equilibrium elasticity of a network of crosslinked semiflexible filaments, spanning the full range between flexible entropy-driven chains to stiff…
Stress relaxation, dynamics and plasticity of transient polymer networks
Fanlong Meng, Robyn H. Pritchard, Eugene M. Terentjev
We propose a theoretical framework for dealing with a transient polymer network undergoing small deformations, based on the rate of breaking and re-forming of network crosslinks an…
The "coin-through-the-rubber" trick: an elastically stabilized invagination
Fanlong Meng, Masao Doi, Zhongcan Ouyang +2
A spectacular trick of close-up magicians involves the apparent passing of a coin through a rubber sheet. The magic is based on the unusual elastic response of a thin rubber sheet:…
Phase diagrams in inflating balloon
Fanlong Meng, Masao Doi, Zhongcan Ouyang
Volume transition of an inflating cylindrical balloon made of rubber under external force is studied based on the non-linear elastic theory for rubber. The pressure difference…
